DPDK for File Transfer and Writing

Dear all,
We are using DPDK to transfer files and write to SSD on the receiver side.
On the sender side, we are splitting the files into 1024-byte packets before sending over to the receiver.
Currently, on the sender side, we are using a worker lcore to retrieve the packets and storing the file data in a buffer while the main lcore writes the data to file using write().
However, we are realizing that the write speed is not fast enough to keep up with the number of packets being received.
We have tried using io_uring to aid speeding up the writing but it seems to be even slower than just writing the file normally.
We would like to check with the community if you have any DPDK compatible suggestions that would help improve file transfer and write performance?
Thank you very much in advance.
Best Regards,Isaac LIM
